INTRODUCTION
BayStar™˙hydraulic steering is brought to you by the manufacturers of SeaStar®, the most trusted name in pleasure boat steering. BayStar allows you to install all of the safety, reliability and comfort of hydraulic steering onto your boats rated up to MAX. 150HP as rated by the engine manufacturer. Combine this with the superior SeaStar Solutions design team, rigid ISO quality control and teamed with the finest materials and precision manufacturing—BayStar continues the tradition bringing comfort and safety to boating.
The BayStar steering system consists of a super low friction helm for smooth comfortable steering, a balanced cylinder–featuring a compact design that fits most splashwells. For your convenience two lengths of 20’ cut to fit tubing are supplied (2 x 20’ length), two bottles of hydraulic steering fluid, and one fill tube for easy fill and purge.
BayStar is NOT recommended in applications with high steering effort (i.e. such as those using high performance engines or boats capable of attaining high speeds), customers should consider upgrading the system to SeaStar/SeaStar Pro steering . This will reduce the steering effort due to the fact that SeaStar steering provides more output power resulting in lower steering effort.
